XMOS Link implementation between XS1-G

[spark]

Hi everyone.
I am trying to make XS1-G be a router which can store and forward the packet received. So i want to use LINK C and LINK D to connect two XS1-G devices. First plan i find recently is making the two XS1-G be 8 cores by modifying the XDK.xn. But it ends up with Failure. I can't boot two devices by only one PC. So i don't know what to do next. Excuse me for my disorder sentences.
